MIP Basis
Type : Selection
Range : The settings listed below
Default : No
By switching on this option the user can pass a basis to CPLEX for a MIP model that can be used by CPLEX for solving the first LP in the branch-and-bound tree search. The value of the general solvers option Accept Basis should also be set to such a value that the basis will be accepted; if the value of the option Accept Basis is 0 then AIMMS wil not pass a basis to CPLEX.
A side effect of passing a basis to CPLEX is that no presolving and crashing will be performed. In case of a MIP model this will in general lead to a loss of performance. Therefore, the default setting of this option is not to load the basis in case of a MIP. Possible values are:
No
Yes
